Attention in the construction of Asphalt sand

Time:2018/08/01 Hits:
1.The intensity can not meet the requirement due to the small particle size stone( less than 3mm).
2.Because the cold mix asphalt is cold mixing, it is not necessary to heat when mixing. It is uneven to mix asphalt and stone , if the particle size is small. It will affect use.
The hot asphalt mixture is mixed at a high temperature of 160℃. Mixing with gravel or mineral powder can increase the density of the asphalt mixture and prevent the road surface permeable.
